LOOM FOR WEAVING PILE CARPETS.

SPECIFICATION forming part of Letters Patent N 0. 732,216, dated June30, 1903. Application filed August 19 1899. Serial No- 727,8Z0. (Nomodel.)

To all; whom, it may concern:

Beitknown that we, HEINRICH PANITSOHEK and J OHANN AHORN, subjects ofthe Emperor of Austria-Hungary, residing at Sarajevo, in the Province ofBosnia, in the Empire of Austria-Hungary, have invented certain new anduseful Improvements in Looms for Weav-' ing Pile Carpets; and we dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to figures of reference marked thereon, whichform a part of this specification.

The knotted carpets known under the name of Smyrna carpets are coarselong-piled carpets with a small number of knots per unit of area (twentythousand to forty thousand knots per square meter) and correspondinglyrough edges, while Persian carpets are distinguished by fineness, shortpile, a large number ofknots per unit of area, (up to five hundredthousand knots per square meter,) and ornamentation finished to theminutest details.

Knotted Persian carpets are, like knotted Smyrna carpets, made by handlabor by winding the figure or pile threads around and knotting them tothe warp-threads by hand in the direction of the weft of the groundfabric.

In doing this either the pile-threads are woundaround a needle, so as toform rows of pileloops, which are then cut by drawing out the needles,or short pieces of thread of about forty millimeters long are employedto produce the tufts or knots, (hereinafter called knots,) whichobviates the use of needles and the cutting of the rows of pile-loops.After a row has been knotted in the manner de scribed the so calledground-pick is inserted, which holds the several pile-threads fast andgives the proper firmness to the carpet.

An essential difference between the coarse and long-pile Smyrna carpetsand the fine and short-pile Persian carpets consists in the formation ofthe knot. In the case of the Smyrna knot the small piece of wool iswound around the warp in the following way: The two ends of the piecefor forming a knot are passed through between the pair of knotthreads tothe surface of the carpet, (see Figure A of the accompanying drawings,)in consequence of which an uneven distribution of the pile takes place,since the pile of both ends passes to the surface betweentwowarpthreads; but no pile passes to the surface between the adjacentwarp-threads of two pairs of knot-threads. It now a carpet with suchknots were out very short, ribs would be produced, because the pilecould not cover the that a perfectly uniform distribution of the pile onthe surface of the carpet is produced.

:Knotted carpets produced in this Way are of course costly on account ofthe protracted and troublesome hand labor and necessitate a considerableexpenditure of wool.

Now this invention relates to a loom for producing fine Persian carpetsin a mechanical manner in perfectly exact imitation of the handwork andwhile employing the knots characteristic of fine Persian carpets, andfor thereby enabling these fine carpets to be produced considerably morequicklyand cheaply.

According to this invention any desired pattern can be produced withoutrestriction as to the number of the colors and with less consumption ofwool than in the case of carpets knotted by hand.

The invention consists, essentially, in that the small pieces of threademployed for pro ducing the knots are drawn by means of tongs out ofbands in which they are held in the order of color corresponding to thedesign to be produced and conducted by the said tongs to a number ofpairs of knottingtongs, which lay each piece of thread to be knotted ina curve around one of the threads of the pair of knot-threads and thentwist the piece of thread around its warp-thread into the form of aloop, whereupon the second knot-thread, located behind the crossed loopends, is loosened by the knotting tongs, and the Persian knot is thuscompleted. The knotting-tongs are arranged on a rising and fallingcarrier by means of the lowering of which the finished knots are pushedup to the finished goods. By the repeated opera-
